Shell Programming and Scripting

Hi All: I'm using sed to replace one line in a configuration file. After replacing that line I would like to display to screen that line plus 10 lines above and below the line that was changed... How would I go about doing that??
Here is my search and replace string....

sed -e "s/ipaddress.info=$IPchange/comm.info=$IPnew/" node.cfg >tmpnode2

What that line does is find the line ipaddress.info and replace the old IP ($IPchange) with the new IP address ($IPnew). So after the switch I'd like to display that whole section where the change was made which is about 10 line above and below the line that was changed....

Is that clear enough ??

Thanks again.. !!

grep from the output file

Code:

grep -C10 "comm.info=$IPnew" tmpnode2

hello please try this hope this will help you.

sed -e "s/ipaddress.info=$IPchange/comm.info=$IPnew/" node.cfg >tmpnode2;
sed -n -e /comm.info=$IPnew/= tmpnode2 | awk '{ str_val="tail +" $1-10 " ./tmpnode2 | head -20" ; system(str_val); }'
